In this study, two Satureja L. species from different localities of Turkey （Satureja hortensis L. and Satureja boissieri Hausskn. ex Boiss.） have been studied to determine their taxonomic classification based on chemical characters. For this purpose, aerial parts of the studied taxa were investigated by HS-SPME/GC-MS. 28, 30 and 29 compounds were identified in S. boissieri from Sanhurfa, BingS1 and Malatya accounting from 90.80%, 91.31% and 92.67% of the whole oil, respectively. 26, 30 and 28 compounds were identified in S. hortensis from Adlyaman, Diyarbaklr, Elazl~ accounting from 93.20%, 92.85% and 92.42% of the whole oil, respectively, y-terpinene （30.4%, 26.5% and 32.1%）, carvacrol （26.4%, 25.2% and 23.3%） and p-cymene （10.5%, 13.2% and 10.4%） were determined as main compounds of S. boissieri in Sanhurfa, Bing6l and Malatya species, respectively. Carvacrol （25.0%, 34.1% and 32.1%）, thymol （28.2%, 20.2% and 28.1%） and y-terpinene （10.1%, 11.3% and 9.4%） were found as main constituents of S. hortensis in Adlyaman, Diyarbaklr and Elazl~ samples, respectively. The chemical distributions of the essential oil compounds in the Satureja pattern were discussed in respect to their chemotaxonomy and natural products.

Diatoms are widely distributed in many temperate areas and some species frequently form extensive blooms in spring. Hence, monitoring the variations of specific genera or species of diatoms is necessary for studying phytoplankton population dynamics in marine ecosystems. To test whether pigment ratios can be used to identify diatoms at a below-class taxonomic level, we analyzed 14 species/strains of diatoms isolated from Chinese seas using high performance liquid chromatography （HPLC）. We normalized all pigment concentrations to total chlorophyll a to calculate the ratios of pigment to chlorophyll a, and calculated the ratios between accessory pigments （or pigment sums）. Cluster analysis indicated that these diatoms could be classified into four clusters in terms of three accessory pigment ratios： chlorophyll c2： chlorophyll Cl, fucoxanthin：total chlorophyll c and diadinoxanthin：diatoxanthin. The classification results matched well with those of biological taxonomy. To test the stability of the classification, pigment data from one species, cultured under different light intensities, and five new species/strains were calculated and used for discriminant analysis. The results show that the classification of diatom species using pigment ratio suites was stable for the variations of pigment ratios of species cultured in different light intensities. The introduction of new species, however, may confuse the classification within the current scheme. Classification of marine diatoms using pigment ratio suites is potentially valuable for the fine chemotaxonomy of phytoplankton at taxonomic levels below class and would advance studies on phytoplankton population dynamics and marine ecology.

El Soplao outcrop, an Early Cretaceous amber deposit recently discovered in northern Spain （Cantabria）, has been shown to be the largest site of amber with arthropod inclusions that has been found in Spain so far. Relevant data provided herein for biogeochemistry of the amber, palynology, taphonomy and arthropod bioinclusions complement those previously published. This set of data suggests at least two botanical sources for the amber of El Soplao deposit. The first （type A amber） strongly supports a source related to Cheirolepidiaceae, and the second （type B amber） shows non-specific conifer biomarkers. Comparison of molecular composition of type A amber with Frenelopsis leaves （Cheirolepidiaceae） strongly suggests a biochemical affinity and a common botanical origin. A preliminary palynological study indicates a regional high taxonomical diversity, mainly of pteridophyte spores and gymnosperm pollen grains. According to the preliminary palynological data, the region was inhabited by conifer forests adapted to a dry season under a subtropical climate. The abundant charcoalified wood associated with the amber in the same beds is evidence of paleofires that most likely promoted both the resin production and an intensive erosion of the litter, and subsequent great accumulation of amber plus plant cuticles. In addition, for the first time in the fossil record, charcoalified plant fibers as bioinclnsions in amber are reported. Other relevant taphonomic data are the exceptional presence of serpulids and bryozoans on the surfaces of some amber pieces indicating both a long exposure on marine or brackish-water and a mixed assemblage of amber. Lastly, new findings of insect bioiuclusions, some of them uncommon in the fossil record or showing remarkable adaptations, are reported. In conclusion, a documented scenario for the origin of the El Soplao amber outcrop is provided.

The 1H nuclear magnetic resonance （1H NMR） fingerprints of fractionated non-polar and polar extracts （control substance for plant drug [CSPD] A and B） from the roots of 12 specimens of Saposhnikovia divaricata （Turcz.） Schischk were achieved with Fourier Transform （FT）-NMR spectrometer and assigned by comparison to each other and to the 1H NMR spectra of the isolated individual compounds. These fingerprints were found to be uniform in terms of the specificity for the implication of all 12 specimens being systematically of the same origin. The uniformity was further affirmed by high performance liquid chromatography （HPLC）, which also revealed exactly identical specificity for the identified S. divaricata species with the 1H NMR appearances of corresponding CSPD on the part of the composition of characteristic constituents when comparing to corresponding individual compounds. This investigation unambiguously shows that the specific signals from the chemotaxonomically significant compounds of chromones and coumarins in S. divaricata are exhibited distinctively in the composite features of both 1H NMR fingerprints and HPLC profiles. The 1H NMR and HPLC profiles established can successfully be used as reference for the authentication of the origin of S. divaricata species as well as for chemotaxonomic studies.
